Description

Toning system for cosmetic compositions

Technical Field

The present application claims priority benefits based on the 2018, 8, 9, japanese korean patent application No. 10-2018-0092760, the entire contents of which are incorporated herein as part of the present specification.

The present invention relates to a toning system for a cosmetic composition that a consumer can directly prepare a cosmetic composition having a color that meets the consumer's various skin conditions and preferences at a store where the cosmetic is purchased.

Background

The cosmetics are classified into a makeup base cosmetic applied to the entire face and a makeup color cosmetic applied to only a small portion of the face. The makeup base cosmetic is intended to cover chloasma, wrinkles, moles, etc. on the face, create clean skin, and the lipstick in the makeup base cosmetic is intended to make the lips more beautiful, the eye shadow is intended to make the eye spirit more beautiful, and the blush is intended to make the cheeks more gorgeous by making shadows around the cheeks, thereby making the face visually beautiful.

Thus, color is an important factor for visual beauty, and for this reason, pigments are applied to dosage forms to provide appearance and color expression.

Recently, as the cosmetic industry grows and consumer demands become diversified, colors of color cosmetics are further subdivided, and demands for standardized products are increasing.

Therefore, since commercially available cosmetics vary in color, it is desired to manage pigments in accordance with color numbers, develop and produce the pigments, and diversify the color numbers to satisfy various and wide ranges of demands of customers.

In general, a color cosmetic product having a color is produced by a production process in which Pigment Bases (PB) as raw materials are mixed and a color prescribed for the color cosmetic product is expressed. At this time, colors are expanded to be diversified based on PB components different from each other, and when colors of respective corresponding color numbers (No. 21, No. 23, etc.) are produced, comparison with standard products and adjustment are performed, thereby providing a product having a certain color to customers.

However, such a method is a method of preparing a specific color, and there is a limitation in reflecting the characteristics of each individual's skin, and therefore, it is considered that a color cosmetic composition is modularized in a certain color (for example, White (White), Yellow (Yellow), Red (Red), Black (Black)), in which a process of standardizing each module to have a certain color is also performed together in consideration of the deviation of the original pigment, and after the modularization is performed, the composition is mixed using equipment in a sales outlet, thereby providing a customer with foundations of various colors.

Detailed Description

Hereinafter, the present invention will be described in further detail to facilitate understanding of the present invention.

The terms or words used in the present specification and claims should not be construed restrictively as meanings commonly or thesaurus, but should be construed as meanings and concepts conforming to the technical idea of the present invention on the basis of the principle that the inventor can appropriately define the concept of the terms in order to describe his invention in the best way.

The term "raw material pigment" used in the present specification means a pigment supplied from a manufacturer. Even the same raw material pigment of the same manufacturer may vary in quality depending on the environment or time at the time of production and supply. The raw material pigment may also be referred to as pigment base (pigment base), and in toning the cosmetic composition according to the present invention, four kinds of raw material pigments, white (W), yellow (Y), red (R), and black (B), are illustrated, particularly for the raw material pigment used in the cosmetic composition for base makeup, but various raw material pigments may be used according to circumstances.

The term "raw material filler" used in the present specification is an additive to be mixed for preventing the raw material pigment from agglomerating when the raw material pigment is mixed to prepare a standard pigment as described later.

The term "standard pigment" used herein means a pigment which is obtained by mixing a raw material pigment and a raw material filler (K) for preventing the raw material pigment from agglomerating in order to overcome the disadvantage of the raw material pigment that exhibits quality variability and exhibits quality stability. The specification pigment may also be referred to as a mixed pigment (mix pigment). In toning the cosmetic composition according to the present invention, four types of standard pigments, i.e., white (MW) standard, yellow (MY) standard, red (MR) standard, and black (MB) standard, are exemplified for the standard pigments used in the cosmetic composition for foundation, but various types of standard pigments may be used depending on the case.

The term "standard filler" as used herein refers to an additive to be mixed for preventing the standard pigment from agglomerating when the standard pigment is blended at a predetermined ratio to prepare a cosmetic composition for color mixing.

The terms "raw material filler" and "standard filler" used in the present specification may refer to the same filler, but may be referred to as a raw material filler and a standard filler, respectively, in order to distinguish the fillers according to the type of pigment used together.

The term "pigment preparation for color matching" used in the present specification is a basic block of a preparation formulation prepared by preparing "standard pigment" into a preparation formulation so that various final preparation formulations can be prepared by simply mixing the "standard pigment" and the pigment prepared by applying the "standard pigment" to a specific preparation formulation. The colorant for toning may be typically an emulsion.

The toning system for a cosmetic composition according to the invention may itself be a device for preparing a customized cosmetic composition.

Toning system for cosmetic compositions

The present invention relates to a toning system for a cosmetic composition capable of toning out a customized cosmetic composition having a color suitable for the skin color of a cosmetic consumer.

Referring to fig. 1, a toning system 1 for a cosmetic composition according to the present invention may include: (a) a skin measurement module 10 for measuring the skin color of a skin measurement object; (b) a control module 20 for simulating a mixing ratio of a coloring agent formulation capable of coloring the skin color based on the data on the measured skin color; and (c) a mixing module 30 for mixing the toning pigment preparations in accordance with the simulated mixing ratio.

In the present invention, the skin measurement module may be one or more selected from the group consisting of a camera, a visible light spectrum measurement device, and a colorimeter as a device for measuring the skin color of the skin measurement target, but is not limited thereto as long as the device can measure the skin color. Preferably, the skin measurement module may be a camera, and when the camera is used, the skin measurement result may be different due to an external light source, and thus the skin color of the skin measurement object may be measured by simultaneously capturing an image of a unit serving as a reference of the skin color, such as a standard color chart.

Data relating to skin tone may be obtained by the skin measurement module. At this time, the available skin color data may be, for example, one or more selected from the group consisting of Lab values, RGB values, and spectral values of respective wavelengths, where L represents Luminosity (Luminosity) as brightness, a represents a combination of red-in-green and b represents blue-in-yellow.

In the present invention, the control module may simulate a mixing ratio of a coloring agent type for toning which can represent the skin color, based on the skin color data acquired by the skin measurement module.

The control module may include: an input unit that inputs the skin color data acquired by the skin measurement module; a calculation unit for determining a mixing ratio of the mixed pigment composition based on the skin color data; and an output unit that transmits the simulated mixing ratio to a mixing module described later.

The colorant formulation for toning may be formulated into one or more selected from the group consisting of an emulsion, a cream, an oil, a gel, a cream, and an essence as a pigment in which a mixed pigment composition prepared by mixing raw material pigments is formulated into a form of a cosmetic composition, but is not limited thereto, and may be formulated into various commercially available forms as a cosmetic.

In the present invention, the mixed pigment composition may be prepared using a raw pigment and a raw filler (K) for preventing the raw pigment from agglomerating.

Although the raw material pigment is supplied from a manufacturer to obtain the same product, there is a quality deviation in each raw material pigment lot (lot) supplied according to the environment and time at the time of production and supply. In addition, even when the toning process is performed using the same raw pigment lot, there is a possibility that the color of the cosmetic composition toned in each process may vary. In other words, even when the same raw material pigment is used and the cosmetic composition is toned by the same process, the raw material pigment may show variation in quality and the color of the cosmetic composition toned with the raw material pigment may be different if the environment and time at the time of production and supply of the raw material pigment are different.

For this reason, in order to complement the disadvantage that the raw material pigment exhibits quality deviation, a mixed pigment composition exhibiting quality stability may be prepared instead of the raw material pigment.

In the present invention, when the cosmetic composition to be toned is a base cosmetic, the raw material pigments may be combined with white (W), yellow (Y), red (R), and black (B) to prepare a mixed pigment composition.

In the present invention, the mixed pigment composition may be prepared in various forms depending on the kinds and mixing ratios of the raw pigment materials mixed in white (W), yellow (Y), red (R), and black (B) as the raw pigment materials.

Since the raw material pigment has a tendency to agglomerate in the form of powder when the mixed pigment composition is prepared, a filler may be mixed with the raw material pigment in order to prevent agglomeration of the raw material pigment, and the filler used when the raw material pigment is mixed is referred to as a raw material filler.

In the present invention, only four standard pigments are exemplified as the mixed pigment composition, but as described above, depending on the kind and mixing ratio of the raw material pigment, standard pigments other than the four standard pigments can be further produced. In the present invention, the four standard pigments are referred to as standard white (MW), standard yellow (MY), standard red (MR), and standard black (MB).

The four standard colors may be prepared by mixing the four raw material colors in different types and mixing ratios of the raw material colors. In this case, since there is a possibility that the pigment agglomerates when only the four raw material pigments are mixed, the raw material filler may be mixed together to prevent the agglomerates.

In addition, in the present invention, the mixed pigment composition may be prepared by grinding (milling). The filler is used in order to prevent the raw material pigment used to prepare the mixed pigment composition from agglomerating, but when the raw material pigment and the filler are mixed by crushing, the quality of the mixed pigment composition may be improved.

In this case, the raw material filler may include one or more selected from the group consisting of polymethyl methacrylate (PMMA), Silica (Silica), Polymethylsilsesquioxane (Polymethylsilsesquioxane), HDI/trimethylol hexyl lactone cross-linked polymer (HDI/trimethylohexylalactone Crosspulym), Alumina (Alumina), Talc (Talc), Sericite (Sericite), and boron nitride (Boronitride).

The raw material filler may be in the form of a sphere or a powder.

On the other hand, when the mixed pigment composition is obtained by grinding, a raw material filler may be used in order to prevent the raw material pigment from agglomerating, but instead of using a filler in the form of powder, oil may be used instead of the filler to prevent the raw material pigment from agglomerating. In this case, the oil may be one or more selected from the group consisting of silicone oils, ester oils, and hydrocarbon oils, but is not limited thereto, and oils that can be used in the art may be used as appropriate depending on compatibility in order to prevent agglomeration of powder.

The grinding may be all grinding used in the art, and a rod crusher may be preferably used.

In general, cosmetic compositions are defined in various colors according to the skin color or preference of users. For example, when an air foundation is used as a foundation, the color thereof is defined as 21, 23, or the like, depending on the skin color of the user.

When an air-cushion foundation composition is prepared using the mixed pigment composition, i.e., four-size pigments and one-size filler, the amounts of the four-size pigments and one-size filler required in preparing the air-cushion foundation composition are fixed.

Since the mixed pigment composition has characteristics that the quality is always constant, when the mixed pigment composition, that is, the four standard pigments are blended in a predetermined ratio, a cosmetic composition having the same quality can be prepared. In this case, when the four standard pigments are blended at a predetermined ratio, a filler may be blended together in order to prevent the standard pigments from agglomerating, and the filler used when mixed with the standard pigments is referred to as a standard filler.

For example, when a number 21 air foundation composition is to be toned using the mixed pigment composition, the formulation ratio of the mixed pigment composition to obtain the number 21 air foundation composition may be set to a fixed value. Since the mixed pigment composition was always of the same quality, when the color of the No. 21 air foundation composition was to be adjusted, the color of the No. 21 air foundation composition always appeared to be the same quality by simply blending the mixed pigment composition at the following blending ratio.

In the present invention, when the mixed pigment composition is used to tone a cosmetic composition, the actual amount of the raw pigment used can be accurately calculated, so that the stock of the raw pigment can be reduced, and the storage or disposal costs consumed when the stock of the raw pigment is generated can be saved.

In the present invention, when a cosmetic composition is toned using the mixed pigment composition, MW, MY, MR, MB, and MK values can be determined using an inverse matrix in the following equation 1. Therefore, even if the manufacturers are different, the production time is different, or even if the same manufacturer uses the raw material pigments having mass variations in the unit of lot number, the MW, MY, MR, MB, and MK values can be obtained by simply adding or subtracting the types and amounts of the raw material pigments to be mixed, and the same quality of the cosmetic composition can be toned regardless of the manufacturers, the production time, or the lot numbers of the raw material pigments.

In addition, the case of using only four raw material pigments is illustrated in the following equation 1, but the case of using only a base makeup cosmetic composition for color adjustment is illustrated, and if necessary, a larger variety of raw material pigments such as a makeup cosmetic composition may be used in the following equation 1.

[ mathematical formula 1]

In the above-mentioned mathematical expression,

W_Y、Y_Y、R_Y、B_Yand K_YEach represents a mixing ratio of white, yellow, red and black raw material pigments used for forming the yellow standard pigment (MY) and a raw material filler,

In addition, in the above formula 1, as parameters fixed for preparing the standard dye,

the W is_W、Y_W、R_W、B_WAnd K_WEach may be 70 to 96, 0.1 to 10, 0.01 to 5, and 3 to 7. When departing from the range, it may be difficult to embody a proper quality of white color when toning the cosmetic composition.

The W is_Y、Y_Y、R_Y、B_YAnd K_YEach may be 1 to 30, 60 to 95, 1 to 30, 0.1 to 15, and 1 to 15. When the range is deviated, it may be difficult to embody a proper quality of yellow color when toning the cosmetic composition.

The W is_R、Y_R、R_R、B_RAnd K_REach may be 1 to 30, 60 to 95, 0.1 to 15, and 1 to 15. When the range is deviated, it may be difficult to embody a proper quality of yellow color when toning the cosmetic composition.

The W is_B、Y_B、R_B、B_BAnd K_BEach may be 1 to 40, 1 to 20, 40 to 90, and 1 to 15. When departing from the range, it may be difficult to embody a proper quality of black color when toning the cosmetic composition.

As described above, the mixed pigment composition is a standard pigment standardized for white, yellow, red and black to be able to tone the color of a cosmetic composition that has been commercialized, however, when the toning system of the cosmetic composition according to the present invention is applied, an optimum mixing ratio can be calculated to be able to tone a cosmetic composition suitable for the skin color of a consumer based on skin color data obtained by directly measuring the skin color of the consumer, and thus a customized cosmetic composition suitable for various skin colors of consumers can be toned by mixing according to the mixing ratio.

In addition, for convenience in management and preparation of the cosmetic composition, the mixed pigment composition may be prepared into a pigment formulation for toning in various formulations as described above and then applied to the toning system of the cosmetic composition according to the present invention.

The mixing module of the cosmetic composition according to the present invention can color the customer-customized cosmetic composition by a simple process of uniformly mixing the coloring pigment preparations for color matching according to the mixing ratio of the coloring pigment preparations for color matching transferred from the control module.

In this case, the mixing module may include a mixer for blending the toning pigment formulation.

Specifically, the mixing module may include: a container (vessel) containing the toning pigment formulation; a nozzle (nozzle) for transferring the coloring agent for color adjustment to a mixer; a control device for transferring the mixing ratio of the colorant for color matching simulated by the control module to a mixer; a mixer that mixes the colorant formulation for toning; and an adjusting section for adjusting the transfer and mixing of the coloring agent for color adjustment.

The mixer may be, for example, an AGI mixer (AGI mixer), but is not limited thereto, and a mixer used in the art for mixing a cosmetic composition may be widely used.

In the present invention, the cosmetic composition to be toned may be selected from the group consisting of a makeup base cosmetic composition, an eye makeup cosmetic composition, and a lip makeup cosmetic composition.

The makeup base cosmetic composition may be one or more selected from the group consisting of air-cushion foundation, powder foundation, foundation solution, foundation cream, and sunscreen cream.

The make-up cosmetic composition for the eyes may be one or more selected from the group consisting of an eye shadow, an eyeliner, and a mascara.

The lip makeup cosmetic composition may be one or more selected from the group consisting of lipstick, lip gloss, lipstick, and lip pencil.

Modes for carrying out the invention

Hereinafter, preferred embodiments are proposed to facilitate understanding of the present invention, however, the following embodiments are merely illustrative of the present invention, and those skilled in the art will clearly understand that various changes and modifications may be made within the scope and technical spirit of the present invention, and such changes and modifications naturally fall within the scope of the appended claims.

In the following preparation examples, a mixed pigment composition as a standard pigment was obtained from a raw pigment by a process of toning a No. 21 air foundation composition (arabian jasmine).

To prepare the No. 21 air foundation composition (arabian jasmine), white (W), yellow (Y), red (R), black (B), and filler K were blended in a weight ratio of 75:5.2:1.8:0.35: 17.65.

In addition, in the following examples, the mixed pigment composition was applied in a toning system for a cosmetic composition, thereby toning a consumer customized cosmetic composition.

Preparation example 1: preparation of Mixed pigment compositions

As the raw material pigments, four kinds of pigments, white (OTS TIO2 CR50) (W), Yellow (OTS-2Yellow LL-100P) (Y), Red (OTS-2Red R-516P) (R) and Black (OTS-2Black BL-100P) (B), manufactured by Daito Kasei Kogyo, were prepared. These raw material pigments belong to the first lot number for each pigment. In addition, a raw material filler (Ganzpearl, spherical powder) (K) was prepared in order to prevent the raw material pigment from agglomerating.

The four raw color pigments and one raw filler were mixed as a mixed color composition exhibiting a constant quality characteristic all the time, and four standard colors were prepared, which were referred to as standard white (MW), standard yellow (MY), standard red (MR), and standard black (MB), respectively. The filler used for blending the four standard pigments is referred to as a standard filler (MK).

The MW was produced by mixing at a ratio of 93.9 wt% W, 0.5 wt% Y, 0.5 wt% R, 0.1 wt% B and 5 wt% K.

The MY is prepared by mixing at a ratio of 5 wt% W, 79 wt% Y, 5 wt% R, 1 wt% B and 5 wt% K.

The MR was prepared by mixing 5 wt% of W, 5 wt% of Y, 79 wt% of R, 1 wt% of B and 10 wt% of K.

The MB was prepared by mixing W10 wt%, Y5 wt%, R5 wt%, B70 wt%, and K10 wt%.

The MK is prepared from the same filler as K.

Preparation example 2: preparation of pigment preparations for toning

All of the four types of pigments of the mixed pigment composition prepared in preparation example 1 were in powder form, and the mixed pigment composition in powder form was prepared in a dosage form that was convenient to handle and to produce by mixing the pigment composition in powder form, so that the pigment composition could be immediately provided to consumers in product form by mixing at a cosmetic store.

In the present preparation example, the pigment composition in powder form is mixed to prepare a dosage form, and the dosage form is referred to as a pigment preparation for toning.

The mixed pigment composition in the form of powder was prepared into an emulsion formulation according to the components described in table 1 below. In this case, as the mixed pigment compositions of preparation example 1 in the following table 1, four pigment formulations for toning white, yellow, red and black, which are respectively referred to as white emulsion (E-MW), yellow emulsion (E-MY), red emulsion (E-MR) and black emulsion (E-MB), were prepared using white (MW), yellow (MY), red (MR) and black (MB) as the four standard pigments.

In table 1 below, a colorless colorant formulation for toning was obtained by mixing without using the mixed colorant composition of preparation example 1, and this was referred to as a colorless emulsion (E-MT).

[ Table 1]

Example 1

White emulsion (E-MW), yellow emulsion (E-MY), red emulsion (E-MR), black emulsion (E-MB) and colorless emulsion (E-MT) were prepared as the colorant formulations for toning prepared in preparation example 2.

The skin color of a skin measurement subject (30 years old, female) was measured by a camera as a skin measurement module, and a Lab value was obtained as skin color data.

In the camera measurement, the standard color chart is photographed at the same time, so that the color deviation caused by the surrounding environment can be corrected.

After the Lab value is inputted to the control module, whether or not a cosmetic composition having a color corresponding to the Lab value can be obtained when the toning pigment formulations are mixed at a certain ratio is simulated, thereby obtaining a mixing ratio of the toning pigment formulations. At this time, the color change due to the combination of the five color composition modules is previously made into a database (database), so that simulation can be performed.

The white emulsion (E-MW), the yellow emulsion (E-MY), the red emulsion (E-MR), the black emulsion (E-MB) and the filler emulsion E-MK were mixed in a mixing module as the toning pigment formulation at the mixing ratio to prepare an emulsion-type cosmetic composition.

At this time, each of the Lab values L ═ 74.7, a ═ 11.73, and b ═ 20.06, and the mixing ratio of the simulated tinting pigment formulations was E-MW: E-MY: E-MR: E-MB: E-MK ═ 7.37:1.12:0.1:0.08: 1.32.

Example 2

The procedure of example 1 was repeated, except that the skin test subjects (30 years old, male) were changed to prepare cosmetic compositions in the form of emulsion.

Here, each of the Lab values is L64.15, a 13.43, and b 22.41, and the mixing ratio of the simulated tinting colorant formulations is E-MW: E-MY: E-MR: E-MB: E-MK: 5.12:22.91:4.06:1.54: 21.49.

Comparative example 1

A No. 21 air foundation composition (allium sambac) was prepared.

Experimental example 1

20 subjects having Lab values (error range ± 0.1) similar to those of the skin measurement subject (30 years old, female) of example 1 were used as subjects, and the subjects were each allowed to use a formulation conforming to each skin and the No. 21 air-cushion foundation composition of comparative example 1 in the same manner as the cosmetic composition prepared in example 1, and used for 7 days.

As a result, 20 subjects who considered that the customized cosmetic composition obtained in example 1 was suitable for the skin color of the subject were observed, whereas only 12 subjects who considered that the No. 21 air foundation composition of comparative example 1 was suitable for the skin color of the subject.

The present invention has been described above by way of the embodiments and the drawings defined in the specification, but the present invention is not limited thereto, and it is a matter of course that various modifications and variations can be made by those having ordinary skill in the art to which the present invention pertains within the technical spirit and the scope equivalent to the appended claims.
